Job Details

The Sr. Scientist performs upstream process research and development experiments within biologics and leads the Microbial Upstream Process Development function.  This role will support early stage research to ensure a smooth transition into Process Development as well as later stage programs.  This includes developing higher performing microbial cell lines; adapting analytical methods for use with upstream samples, using bench-top bioreactors to characterize microbial cell lines in high cell density fermentation processes; authoring technology transfer documents; assisting in the  transfer of microbial fermentation processes onsite at commercial manufacturing facilities; and, continuing to support ongoing manufacturing needs.  

Additional Responsibilities:

  • Manages the microbial upstream process development, providing guidance and training to junior scientific as needed and ensures adherence to company policies and quality requirements.
  • Set-up, operation and maintenance of bench-top bioreactors (2L to 10L) for microbial fermentation. 
  • Performs in process sampling and off-line metabolite and cell density measurements during fermentation runs.
  • Adapts analytical techniques to assess product quality in fermentation samples, such techniques may include HPLC, SDS-PAGE, and ELISA.
  • Executes shake flask screens to identify improved cell lines.
  • Uses design of experiment (DOE) approaches to identify superior process parameters.
  • Exercises technical discretion in the execution and interpretation of experiments that contribute to project strategies.
  • Maintains familiarity with current scientific literature.
  • Contributes to scientific literature and conferences.
